12.14 Cycle 26 Calibration Program
The Cycle 26 calibration plans for COS continue the routine calibration and monitoring programs performed in previous Cycles. Brief descriptions of the programs are listed in Table 12.2. The full calibration plan for Cycle 26 is listed in Table 12.17.
Table 12.17: Cycle 26 Calibration Programs.
